A PC and PS5 Issue

First of, i would like to say hello, i hope you are all doing well.

I have an issue, i bought BF6 on pc and i bought BF6 to my brother aswell. But the thing is that i have the same email address and the same EA account on both. We are sharing for some reason the same account and can't play together since the progress is the same on both. Is there any way to fix this so me and my brother can play together and him having different progress?

Thanks in advance.
